Signs rule for multiplication and division When two positive numbers are multiplied or divided, the result will have a positive sign. (+) x (+) = + (+) ÷ (+) = + When two numbers are multiplied or divided, one with a positive sign and the other with a negative sign, the result will have a negative sign. (+) x (-) = - (+) ÷ (-) = -

To sum it all up and to make everything easy, the two most important things to remember when you are multiplying integers or dividing integers are: When the signs are different, the answer is always negative. When the signs are the same, the answer is always positive.

When you have the same sign twice (+ + or − −), they’ll turn into a single plus sign (+). When you have different signs (+ − or − +), they’ll turn into a single minus sign (−). Multiplication and division follow the relationships between numbers we know from the multiplication table. But how do you take the sign into consideration?
